MathML Test : Integrals and Differentials

This is a simple test to check if symbols used for integrals and differentials can be displayed. For the integral symbols that are mentionned in the operator dictionary entries the attributes are largeop="true" and stretchy="true".

1. check each integral symbol (simple, double, contour...)
2. check if integrals symbols are stretched
3. check the differential symbols

• Simple : ${\int }_a^{b}f\left(x\right)dx$
• Double : ${\iint }_a^{b}f\left(x\right)dx$
• Triple : ${\iiint }_a^{b}f\left(x\right)dx$
• Contour : ${\oint }_a^{b}f\left(x\right)dx$
• Double Contour : ${∯}_a^{b}f\left(x\right)dx$
• Triple Contour : ${∰}_a^{b}f\left(x\right)dx$
• Clockwise : ${∱}_a^{b}f\left(x\right)dx$
• Clockwise Contour : ${∲}_a^{b}f\left(x\right)dx$
• Counter Clockwise Contour : ${∳}_a^{b}f\left(x\right)dx$
• Nabla : $\nabla f$
• PartialD : $\frac{\partial f\left(x,y\right)}{\partial x}$
• CapitalDifferentialD : $Dy$
• DifferentialD : $dx$
